OSRAM CSLNM1.TG & CULNM1.TG 1mm², CSLPM1.TG & CULPM1.TG 2mm²

Oh, apparently I learned something I didn’t know, I assumed monochrome was simply single color. I What is the difference between monochrome and converted? Effective difference as I somewhat understand the phosphor converted. I expect it is the spike in wavelength in the blue freq…

On a separate note, with it being phosphor converted will a RTL collar work with these?

Thanks for the link.
I could not find what is the wavelength of emitted light in their datasheet!!!

Good point. Their spectral plot shows it peaking just below 525nm and the top of the curve spreading between 525 and 550,but they don’t bin them. In fact the only “bin” they list is “A” and they only associate that against brightness bin 5P

how is the beam in the 2mm^2 version? I see the die is rectangular, I wanted to use it in a C8 host but I don’t know if the beam is going to be right or this led should be used only with aspherical lens

You will not notice anything different in the beam when the 2mm2 Flat White is used in a reflector light.

the sofirn c8t driver can be bought from sofirn store on ali. its max 4.5 amp according to them.
Is there a reason this wouldnt work?
its pwm tho so regulated should be better right?

this is still a DD driver so no regulation at all, just their main Mosfet sucks so bad it has limit the current a bit, but not with ultra low Vf LEDs

Ow oke thanks for the response. I already ordered some 7135s so i guess my soldering skills will be called upon :wink:

MF04 on Osram 2mm² vs stock

NICE!

Which is which please?

Osram has cooler tint and tighter/sharper beam, not as fuzzy.

Thank you Enderman.
Edit.
What about data-throw?

Osram on left, stock on right.
In real stock is more warm than on the picture and Osram is less blue.
T:2s ISO 200 F: 4
I didn’t measured throw.
Yesterday was foggy.
From 5m osram has a hole inside the beam.
I guess the correct distance to measure is around 25 m.

You are right! :+1:
I measured osram led lights and GT xhp35HI version at 15, 20, 25m
If you have a hole in the beam at 5, 10m in MF04 with osram you are close to good focus. From the image I think it is perfectly dialed in.

Should any thrower have a hole in the beam at short distance ?
I still didn’t succeed dialing my Emisar D1 with Black Flat correctly … only 60kCd

Actually yes, the beam needs some distance to fully form. But depending on the light this can be only a couple of centimeters.

Yes.

The distance in which the hole dissappears depends on the relation of the diameter of the reflector to the size of the LED. The bigger it is, the longer the distance.

I documented my experiences regarding this topic here and did some simulations here and here (in German).

All focused lights should have a hole in their beam at close range. Even small edc type lights will have a donut-hole hotspot in the first couple of inches of their beam. Super throwers will have this hole for many meters.

I wish someone would make a new thread solely about focusing thrower LEDs with steps, tips and best practices. It’s one of those things people talk about but never in detail. When I made a thread about how crappy my spring bypasses were everyone chimed in and I think it was very helpful basic topic (to me) to rehash after so long.
